Assigning NatureServe Conservation Status Ranks to Rare Texas Plants

NatureServe Conservation Status Ranks assess the conservation status of species at the global, national, and sub-national scale (G-rank, N-rank, and S-rank, respectively). These ranks assess the risk of species extinction at the global scale, or extirpation at the national and subnational scales. A standardized methodology and rank calculator have been developed to remove the ambiguity from the process of assigning ranks and ensure a transparent, consistent, and rigorous assessment to justify ranks. Consistency and transparency are essential as these ranks are widely used by conservation professionals, private organizations, and government agencies, and they often form the baseline for management of rare species (Faber-Langendoen et al. 2012).

Texas Parks and Wildlife is responsible for assessing the almost 450 plant taxa on the Species of Greatest Conservation Need (SGCN) list in the Texas Conservation Action Plan (2012). A complete re-assessment of all SGCN is needed and is currently underway by TPWD using the NatureServe Rank Calculator. BRIT botanists received a Conservation License Plate Grant to re-assess ranks for several rare species in North Central Texas, as well as several species which are being evaluated for listing under the Endangered Species Act.

My Research Internship: An education beyond expectations

This article was written by Erin Flinchbaugh, 2019 BRIT Summer Intern and student at University of Texas at Arlington. Erin interned with Conservation Botanist Kim Taylor , working with the NatureServe Conservation Status Ranks and Mapping Rare Plants on Roadsides projects within the Texas Plant Conservation Program . Beginning my internship at BRIT, I expected many of my passions to be shared by the people surrounding me: a passion for our natural world, its conservation, restoration, and preservation were the common ground we shared. When I started my internship I didn’t expect to find myself invested in the direction of tiny hairs faced on a stem, squatting down in the dirt (and once an ant pile) to further inspect and then debate the trichomes. This summer I was mentored by Kim Taylor...
